The biological equivalent is "allopatric speciation," an evolutionary process in which one species divides into two because the original homogenous population has become separated and both groups ...

Vicariance is the emergence of geographic barriers to dispersal and gene flow, which spatially isolates populations and may lead to the formation of new species (i.e., allopatric speciation ...

I expect you to read: Avise, J.C. 2004. Chapter 7: Speciation and hybridization. In Molecular Markers, Natural History and Evolution (2nd edn.). Chapman and Hall, New York. Having at least briefly ...

A new study co-authored by researchers at Indiana University sheds light on how the forces that shape mountain ranges also influence the evolution of species. In the study, “Direct effects of mountain ...

How do new species form? Like most areas of Evolutionary Biology, research related to the formation of new species - 'speciation ' - is rich in historical and current debate. Here, we review both ...

But the origin of a species, otherwise known as speciation, takes thousands, maybe millions of years, a fact that makes it extraordinarily difficult to study. Consequently, the process of speciation ...
